AKTAKOM APS-4233 is a high-precision regulated DC power supply which is widely used in debugging process, repair and laboratory research. Besides other applications its a perfect power supply for science investigation, college, factory, electronic appliance maintenance and etc.

APS-4233 outputs smoothly adjustable stabilized DC voltage and stabilized current. The model has 4 outputs: two outputs are adjustable and two outputs are half adjustable.

The two adjustable outputs can also be selected for constant voltage or constant current, designed in high stability and performance circuit. In constant voltage state the output voltage can be arbitrarily adjusted from 0V on in the nominal range; and in the state of constant current the output current can be adjustable from 0A on in the nominal range. The two adjustable outputs can be connected in parallel or in series.

The other two half adjustable channels are as follows: one is 36.5V/3A and the second one is 815V/1A. These channels have good stability and ripple factor and it has reliable overload protection to protect APS-4233 against being damaged whenever overload or short circuit.

This instrument is rather compact, this allows to occupy a minimal space and organize a high performance work area. Other features of this bench power supply include high performance, short circuit protection availability, modern design etc.

APS-4233 DC power supply (analog of M10-QP303) has a digital indication, all information is displayed on 4 3-digit LED displays.

Frequently Asked Questions

  • May I use AKTAKOM power supplies to charge accumulators?

  • May I use AKTAKOM power supplies to charge accumulators?

    AKTAKOM power supplies cant be used for accumulator charging since it may cause the accumulator breakage (recharge, electrolyte boiling, extra pressure of the internal gas which will lead to the accumulator explosion). Accumulators should be charged with the current source which controls the accumulator voltage and regulates the charging current accordingly. When the required accumulator voltage is achieved such type of source simply stops the charging process, its name is a charging device.


    AKTAKOM APS-4233 es una fuente de alimentacin regulada por CC de alta precisin que se usa ampliamente en el proceso de depuracin, reparacin e investigacin de laboratorio. Adems de otras aplicaciones, es una fuente de alimentacin perfecta para investigacin cientfica, universidad, fbrica, mantenimiento de aparatos electrnicos, etc.

    APS-4233 emite voltaje de CC estabilizado suavemente ajustable y corriente estabilizada. El modelo tiene 4 formas de salida: dos formas son ajustables y dos formas son medio ajustables.

    Las dos salidas ajustables tambin pueden seleccionarse para voltaje constante o corriente constante, diseadas en un circuito de alta estabilidad y rendimiento. En estado de voltaje constante, el voltaje de salida puede ajustarse arbitrariamente desde 0V en el rango nominal; y en el estado de corriente constante, la corriente de salida se puede ajustar desde 0A en el rango nominal. Las dos salidas se pueden conectar en paralelo o en serie.

    Los otros dos canales ajustables son los siguientes: uno es 3 6.5V / 3A y el segundo es 8 15V / 1A. Estos canales tienen una buena estabilidad y un factor de ondulacin y una proteccin confiable contra sobrecargas para proteger el APS-4233 contra daos en caso de sobrecargas o cortocircuitos.

    La estructura de la unidad es bastante compacta, esto permite que el APS-4233 ocupe un espacio mnimo y organice un rea de trabajo de alto rendimiento. Otras caractersticas de esta fuente de alimentacin incluyen alto rendimiento, disponibilidad de proteccin contra cortocircuitos, diseo moderno, etc.

    El APS-4233 tiene una indicacin digital, toda la informacin se muestra en 4 pantallas LED de 3 dgitos.


    • 4 LED de 3 dgitos
    • Indicacin separada de corriente y voltaje
    • Indicadores de estabilizacin de corriente (CC) y tensin (CV).
    • Proteccin contra cortocircuitos
    • Modo de estabilizacin (corriente, tensin)
    • Modo de seguimiento para canales ajustables.
